Hmmm….I got this for my UNO, to drive a single Pololu 1101 gearmotor. I tried the sample sketch and the motor only ever moves in one direction, and does not change speed?
I’m using a 7.4v l-ion battery to provide power to the uno.
Does the driver get confused if only one motor is connected?
Oh, and I confirmed dir-a is set to pin 3
